Big Torque on a Budget

Free Shipping!

Chevrolet Performance's 454 HO crate engine is classic in its own time, offering enthusiasts an affordable Big-Block combination with performance specs that will make you think it's 1970 all over again - with 438 horsepower and 500 asphalt-wrinkling lb-ft of torque. The foundation of the 454 HO is a brand-new, updated cylinder block, which incorporates many strength and performance design enhancements - making it a smart and economical alternative to rebuilding. We also add an all-forged reciprocating assembly for maximum durability, a roller camshaft, and a set of rectangular-port iron cylinder heads. We deliver the 454 HO with a water pump, balancer, 14-inch flexplate, and aluminum intake manifold. Add a carburetor, ignition system, and starter and your budget Big-Block will be ready to roar.
